Project Overview

Betfin is a decentralized gaming and staking platform that allows users to enjoy decentralized games with option to generate rewards as a "casino owner". There are 2 types of games and 2 types of staking on Betfin - conservative and dynamic staking and games. Conservative games are games where users play one against other without a risk for a platform where conservative staking generates 3.6% winning fee. Dynamic staking represents a fully decentralized casino where the winner decision is based on the random number generated by Chainlink VRF. In dynamic staking you become a casino owner and generate profit if users looses and opositely - you provide a liquidity for winnings. Important part is affiliate that allows you to generate profit from users stake and bets with extension in binary tree. Last but not least is partnership system that allows anyone to create own decentralized gaming branch.

Rewards by Severity

Additional reward of 10% up to 70,000 USDT for finding a critical bug that may result a direct damage that is fatal for the project. Such bug can be drain of funds from the contracts, possibility to mint tokens or change of consensus that would result such direct damage.

Additional reward of 10% market value of tokens involved (min 5,000 up to 30,000 USDT) for finding a critical bug that will result permanent freeze of assets or permanent shutdown of the contract functionality.

In-Scope Vulnerabilities
Only the following impacts are accepted within this bug bounty program. All other impacts are not considered in-scope, even if they affect something in the assets in scope table.

Temporary freezing of funds for any amount of time
Access control is bypassed - including privilege escalation
Theft or permanent freezing of unclaimed yield
Medium

Users could lose funds due to rounding
Griefing (e.g. no profit motive for an attacker but damage to the users or the protocol)
Weak random sources
Low
Non-intuitive return values
Important gas optimizations
Smart contract fails to deliver promised returns - but doesn’t lose value
Missing events for functions that change critical parameters

Program Rules
  • Please provide detailed reports with reproducible steps. If the report is not detailed enough to reproduce the issue - the issue will not be eligible for a reward., Submit one vulnerability per report - unless you need to chain vulnerabilities to provide impact., When duplicates occur we only award the first report that was received (provided that it can be fully reproduced)., Multiple vulnerabilities caused by one underlying issue will be awarded one bounty., Make a good faith effort to avoid privacy violations - destruction of data - and interruption or degradation of our service. Only interact with accounts you own or with explicit permission of the account holder., Do not attempt to conduct post-exploitation including modification or destruction of data - and interruption or degradation of services., Do not attempt to perform brute-force attacks or denial-of-service attacks., Do not attempt to target employees or customers including social engineering attacks - phishing attacks or physical attacks.
The following activities are prohibited by this bug bounty program:
  • Automated testing of services that generate significant amounts of traffic., Public disclosure of an unpatched vulnerability in an embargoed bounty., Social engineering (e.g. phishing
  • vishing
  • smishing) of any kind.
